The selective toxicity of insecticides against insect pests of rice and their natural enemies
Applied Entomology and Zoology 8 (4), 220-226
Abstract: The relative toxicity of fourteen insecticides to two rice pests (Nephotettix cincticeps and Chilo suppressalis) and their predators (Lycosa pseudoannulata and Conocephalus maculatus) was studied. Among four carbamates, carbaryl was least toxic to C. maculatus. Of the organophosphates used, fenitrothion, pyridafenthion and tetrachlorvinphos were highly toxic to C. maculatus, which was very susceptible to six organophosphates. The toxicity of chlorophenamidine was low to C. maculatus, and the toxicities of gamma-BHC and methomyl were high.
